Security Clearance:

Position requires a Department of Energy (DOE) Q-level security clearance to start.

Position requires an active Department of Energy (DOE) Q-level security clearance or active clearance with another U.S. government agency (e.g., DOD) to be considered for this position.

Position requires SCI access.

Position requires a Department of Energy (DOE) Q-level security clearance and SCI access. SCI access may require a polygraph examination.

Sandia is required by DOE to conduct a pre-employment drug test and background review that includes checks of personal references, credit, law enforcement records, and employment/education verifications. Applicants for employment must be able to obtain and maintain a DOE Q-level security clearance and SCI access, both of which require US citizenship. SCI access may also require a polygraph examination. If you hold more than one citizenship (i.e., of the U.S. and another country), your ability to obtain these levels of access may be impacted.

Applicants offered employment with Sandia are subject to a federal background investigation to meet the requirements for access to classified information or matter if the duties of the position require a DOE security clearance. Substance abuse or illegal drug use, falsification of information, criminal activity, serious misconduct or other indicators of untrustworthiness can cause a clearance to be denied or terminated by the DOE, resulting in the inability to perform the duties assigned and subsequent termination of employment.
